A convenient method for synthesis of nano-titania thin films from aqueous TiO2 precursor sols
Anatase TiO2 thin films were prepared on glass substrates by dip-coating method with TiCl4 as the Ti precursor hydrolysis in a mixed solvent of alcohol and water.The effects of preparation parameters such as the alcohol species,the alcohol/water (A/W) ratio,and the dosage of TiCl4 (the volume ratio of TiCl4 and mixed solution) were investigated.The best preparation condition was optimized that with the isopropanol / H2O volume ratio of 65∶35,the dosage of TiCl4 at 3%.XRD,SEM,TEM and UV-Vis photospectroscopy were used to analyze the characteristics of the solution and films.The films have a high hydrophilicity after illuminating with ultraviolet light,it have a good adherence and can be used as an efficient photocatalyst.
